So there is this manager at the bowling alley who is absolutely terrible at her job and just really can't handle anything life throws at her. Anyway, she found out one day that she is possibly going to get fired because she slept with one of her coworkers. So what does she do? Deny it? Give up? Talk her way out of it? Nope. She files EIGHT sexual harassment charges against her other coworkers so that she is basically unfireable because the company would get sued. So she will inevitably be fired, but she wanted to make sure she left a blaze of fucking hell behind her.

No reason not to. If you lose, you pay nothing for it. If you win, they can't ever get rid of you or at least they have to pay a lot to do so. Instituting at least some form of loser pays as well as getting rid of contingency based lawyering (where you pay nothing if you lose but the lawyer takes a huge chunk if you win) would fix a lot of that.
